8-Channel Analog Input Module is used to interface measurement circuits. Each channel can be separately configured to measure resistive sensors, current loops or voltage messages. Configuration is done using setup jumpers. Analog to digital converter is high precision 20-bit sigma-delta converter, which has better than 110 dB rejection at 50 Hz. Analog Input module can also be used to interface potential free contacts. All important values are saved to eeprom during power off. Module’s address and communication speed is selected using onboard dip-switch.

Note: Analogue Input module returns a "raw" A/D-converter value over the Modbus. This value is required to be scaled in the Modbus master accroding to the requirements. Please look at the configuration guide for more details.
